EDUARD VON IIAKEN, OF CHARLOTTENBURG, GERMANY, ASSIGNOR OF ONE- IIALF TO DOCTOR MARTIN \VALDECK, OF BERLIN, GERMANY.

SWITCH-OPERATING DEVlCE.

SPECIFICATION forming part of Letters Patent No. 584,174, dated June 8, 1897.

Application filed February 9, 1897. $erial No. 622,606. (No model.)

To all whom it may concern:

Be it known that I, EDUARD VON HAKEN, a subject of the Emperor of Russia, residing at Oharlottenburg, in the Kingdom of Prussia, Germany, have invented new and useful Improvements in SwitclrOperating Devices, of which the following is a specification.

This invention relates to that class of switch-operatin g devices in which the switch- IO point is connected with a lever or other operating device located on the track and in which said operating device is actuated by engagement with the passing car or a part carried thereon.

The invention will be fully described hereinafter and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indizo cate corresponding parts in all the figures.

Figure 1 is a plan view of the invention as applied. Fig. 2 is a similar view showing the parts in different position. Fig. 3 is a transverse section taken through the plat- 5 form of the car and extending to the track.

Fig. 4 is a plan view of the lever, and Fig. 5

is an edge view of the same.

The railway has the usual rails a and b, from which the switch-rails a and Z2 pass. 0 The switch-point Z is located between the rails b and b and controls the switch. The operating-lever has three arms 0, c, and c and turns on an axis 0 located centrally in the bed of the railway. The arms 0 and c of the lever extend at an obtuse angle to each other and rearwardly from the switch, and the outer terminals of the arms 0 and c are provided with cams t and '5, respectively. The terminals of the arms 0 and 0 respectively, extend through openings f and f in the rails a and b, so that the cams i and i will alternately lie within the flange-grooves of the rails. When one cam is within the groove of its adjacent rail, the other cam will be outside its groove, and vice versa, as the drawings clearly show.

The third arm 0 of the operating-lever is alined longitudinally with the arm 0, and consequently extends at an acute angle to the arm 0 and to the switch-point Z. The

end of the arm 0 is movable in an opening embracing the rods cl and d, the springs being each connected at one end with the rods and at the other end with the sleeves.

lVith the parts arranged as in Fig. 1 if it be desired that a car moving in the direction of the arrow in said figure should pass on the switch-rails a ahd b the rod cl should be depressed, causing it to run through the flanged groove of the rail Z) and strike the cam 11. This will turn the operating-lever and cause the point Z to be moved to the left, whereby the car is thrown from the main rails to the switch-rails. If the next car is to pass along the main rails, the rod d of the said next car should be depressed so as to engage with the cam i, which cam will have been previously moved into its opening f. The engagement of the rod d with the cam i will turn the operating-lever in the direction opposite to the direction in which it is first turned and return the switch-point Z to the position shown in Fig. 1.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of a switch-point, and a lever having three arms, one of said arms having two pins embracing the switch-point, and the other two arms being each provided with an upwardly-projected cam, whereby the lever may be turned by the movement of an object against either of the cams, substantially as described.

2. In a switch, an operating-lever having three radial arms, one of said arms having pins capable of receiving a switclrpoint be tween them, and the other two arms each having a cam by which the lever may be actuated, substantially as described.

3. The combination of a switch-point, and In testimony whereof I have signed my a lever having a plurality of arms, one of name to this specification in the presence of which has two pins embracing the switchtwo subscribing Witnesses.
